What are we about?



We are passionate about showcasing the business sector as a leader in providing social environmental and economic wellbeing. We are equally passionate about showing our clients how they can benefit from investment in sustainable and responsible business practices.



We believe in business as a force for good. The business sector has the ability and a responsibility to give back that goes far beyond economic value. It can and should be a protector of our natural environment and a catalyst for change in the system of social provisions in our community.



We strive to offer more intelligent data capture for our clients. To show them the rich and useful data hidden within their business and prove the difference this can make to strategic decision making and ultimately, their future as a sustainable company.

Our Vision

SustainIQ provides companies with revolutionary insights into their investments in sustainability,
ensuring greater strategic impact and more ambitious targets for the future.

Our Impact

At SustainIQ, we are passionate about making a difference in the world. We believe the success of our business is driven, not just by profit, but by the positive impact we can have. We are therefore committed to giving back.

The UN Sustainable Development Goals

The Sustainable Development Goals are a call for action by all countries – poor, rich and middle-income – to promote prosperity while protecting the planet. They recognize that ending poverty must go hand-in-hand with strategies that build economic growth and address a range of social needs including education, health, social protection, and job opportunities, while tackling climate change and environmental protection.

The Cause

UN Sustainable Development Goal 7 – Affordable & Clean Energy

Most of us in the developed world take access to energy for granted. Light bulbs turn on at the flick of a switch; we have instant and constant access to power for our many devices and we heat and cool our homes without a second thought.

It's a very different story for the 789 million people globally who still can't access electricity. Many rely on kerosene lamps that release harmful emissions, provide a poor source of light, are expensive to run and are extremely hazardous.

Energy poverty is also a climate issue and therefore solar lights offer a real and sustainable solution to help combat energy poverty now.

Our Commitment

With every new subscription to SustainIQ, we provide solar lighting that helps 334 people, saves families £9,875, gives children 62.4k hours of extra study time, decreases CO2 emissions by 65.8 tonnes and allows 162 people in a developing country to live healthier lives. We do this in partnership with Solar Aid.

Solar lighting is safe, clean and affordable and will open up opportunities that most of us take for granted, but of which those kept in the dark can only dream. It will allow families to earn, learn and feel safe after dark; provide opportunities for income, a livelihood and independence - all using the power of the sun.

Working with our customers, we can provide a family with their first step on the energy ladder and help contribute to SDG 7.

Meet the Co-Founders

SustainIQ was formed by its two co-founders Liam McEvoy and Maria Diffley. The pair met at an industry award ceremony in 2017 and over a glass or two of wine, got chatting about the many challenges sustainability presents to businesses who are looking to operate in a more sustainable and responsible manner. Many more conversations followed, and they soon realised there was a real need to create a solution that would help organisations use their sustainability performance to drive business improvement. And so, SustainIQ was born. An online platform that allows organisations to harness their business intelligence that previously was not being considered in the strategic decision-making process.

Both Maria and Liam have strong backgrounds working in sustainability. Maria has worked in both the public and voluntary sectors and holds an MSc in Sustainability & CSR. Liam has worked with construction and manufacturing clients for over 15 years developing sustainability strategies for their corporate clients. He holds a BSc (Hons) Environmental Management.
